the new coronavirus Covid 19
We recently heard a lot about the epidemic of human infection with the new coronavirus (SARS CoV-2) that causes Covid 19 disease that has spread around the world and infected more than seven million people and has so far killed more than half a million people, and we feel it can spread to human bats .
Years ago we discovered swine flu, bird flu, and corona virus, which were transmitted to us by camels and even before SARS, which was also transmitted to us by bats. Throughout history we have known many epidemics, such as the plague of a mouse. What is the history of all these diseases that come to us from animals?
In fact, over 70% of epidemics, germs, viruses, and various infectious diseases are transmitted to humans by animals, and in 2013 biologist David Cohen published an important book on the spread of diseases from animals to humans entitled "Spillage" that describes the history of the spread of infectious diseases. From animals to humans, focus on transmitting the virus from animals and forecasting the recurrence and spread of local viral and global epidemics in the near future.
* What are viruses?
Viruses are very simple organisms in composition that have not only the properties of life in addition to their ability to reproduce, also in the sense that they cannot reproduce, but they need parasitism in the living cell to be used as a vital activity in favor of reproduction of the virus. Exploiting the living cell's genetic system to benefit the existing parasite. . . In other words, viruses are considered coercive parasites and can survive only by parasitizing other organisms.
* What is the virus synthesis?
The virus is made up of a simple set of hereditary nucleic acids, which can be of type RNA or DNA, and surrounds this self-coated range with a single layer of proteins and fatty substances. It does not contain other substances inside, because it does not perform any vital activity and does not eat, drink, move, think or remember.
Billions of viruses exist and parasitize almost all types of living organisms ... in bacteria, plants, and animals, and it is not in the interest of any kind of virus to destroy living organisms. In which they live and depend on it to continue to exist. And reproduction.
Each type of virus is suitable for a specific type of organism in which it can reproduce without causing harm, because it is a "natural" incubator, but the disease can occur when a type of virus passes from one natural incubator to another. Living organisms, the genetic characteristics of viruses change constantly, radically and quickly, especially in viruses whose genetic material consists of RNA.
And when the genetic material of the virus changes, in the vast majority of cases, the natural incubator loses and cannot continue to exist and reproduce, and is forced to reach another live incubator, and that means - to say that it is obliged to transfer to living cells that absorb the new change in their genetic makeup, and these The process fails viruses and disappears. The new cell, and perhaps billions, and sometimes before the new virus encounters a new living cell that is proportional to the ability to enter and multiply in it, and it is always present in its new incubator, and not through thinking and planning, it is clear that it happens by chance because, as we said before: Viruses do not Think, plan or move yourself and the properties closest to the cells of the organism (the new incubator), the closer the characteristics of the cell in the previous incubator, the more likely it is to spread with the new virus. Therefore, we should not be surprised by the frequent transmission of mammalian viruses (bats, pigs, and monkeys) to humans and the possibility of increasing the new reproductive virus if it is able to transmit not only to the new incubator member (bats only) in humans), but if it can transmit the first case between members New incubator, or from one person to another, "for example, in the Ebola and SARS epidemic, and we see that the second case is now occurring in the new Corona epidemic.
* Civilization of social networks and acceleration of transportation.
Man has been reunited with plants and animals throughout his life for hundreds of thousands of years and there is no doubt that viruses are transmitted from animals to humans through contact and communication during hunting, rehabilitation, breeding or consumption of wild animals. This connection caused many known diseases and epidemics. A man, including the elderly, such as malaria, plague, tuberculosis, smallpox, Maltese fever ... some are new, such as monkey aids, Ebola bats and others.
Perhaps we have developed and accelerated the means of communication and publishing all over the world, and our increasing number is all factors of civilization and progress, but at the same time, this has led to an increase in our relations. With new animal species, thus increasing the chances of infection with new viruses from different wild animals to humans. As it happened when the new Coronavirus spread from bats to humans on the wildlife market in Wuhan, China, then spread to humans in the local Asian epidemic. East, and then the epidemic spread to a global epidemic thanks to the development of rapid transformations, big events and the dimensions of social media.
* Are epidemics repeated?
Given the current development of human societies, the real question is not whether epidemics can recur, but when they will occur. Will the new epidemics be more serious? Or will we be better prepared?
